A robust a posteriori error estimator for the Oseen problem
Muhammad Afzal, Naveed Ahmed, Volker John
A residual-based a posteriori error estimator is proposed for the incompressible Oseen problem in the convection-dominated regime. The SUPG/PSPG/grad-div stabilized finite element…

Adaptive Finite Elements with Algebraic Stabilization for Convection-Dominated Transport
Naveed Ahmed, Abhinav Jha
We present a numerical investigation of residual-based a posteriori error estimation for finite element discretizations of convection--diffusion equations stabilized by algebraic f…

A mixed FEM for a time-fractional Fokker-Planck model
Samir Karaa, Kassem Mustapha, Naveed Ahmed
We propose and analyze a mixed finite element method for the spatial approximation of a time-fractional Fokker--Planck equation in a convex polyhedral domain, where the given drivi…
